' To-aZZ whom it may concern Be it known that I, ROBERT CHARLES P ns- SELL, subject of the King of Great Britain,

residing at WestgateStreet, Bath, Eng

land, have invented new and useful Improvements in Signaling Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to signaling apparatus and has for its Object to provide Fig. 2 is a vertical section on the line 2+2 of Fig. lithe cover being removed.

3 is an end elevation.

.F,1g.,4s a sectional plan on theline 44 ofFig. 1.

able radial plates or keys;

Fig. 6 is cross section-pf the wheel on the line 66 of Fig. 1=drawntoalarger scale. and showing plate retained "by annular coiled spring. Referring to the drawings which. illus trate a preferred. construction of apparatus embodying the principle .ofmy invention.

ofthe movthree'means of. signaling areemployed,- two.

by visual signaling and one by sound. Qne means of visualsignaling comprises ajre movable flag learned by an arm 2 adapted to be moved in an arcof a circle after the manner of Morse signaling. Thisarm '2. whichis-preferably removable for packing purposes and may be-curved or straight is pivoted at a point near itslower end by meansof a pin 3. l 3

Movement is imparted to the flagarm 2 by means of a vertically disposed: arm 7 pivoted at its lowermost end by means of a pin casing'lO. ,This arm 7 carries at its upper end a pin llwhich engages a slot 12 provided in the flag arm 2, 0 that any. arcuate movement imparted to the pivoted armfi will be transmitted to the flag arm 2. To

prevent the flag arm from falling belowthe 8 projecting from an endwall 9 of a boxlike L conventional ready position illustrated by Fig. 2, an abutment "12? of 7 rubber or other suitable material is provided against which I is adapted to engage, the lowermost part of the flag arm 2.

The flag arm 2 and Y ed formovement across one-face of a plate 13 secured to the: end wall) of the casing 10. .This plate 13 which may if desired carryz the, pivot pins 3 and8 is formed with a transverse channel 14;. the opposite side portions 15016 which are slotted at 16to' receive and serve as aguide forthev arm 7 the arm 7, are mount Secured to'the arm 7', orit desired formed 7 integrally therewith is 1 a -t-ra-nsverse channel member or portion 17 having a substantially centrally disposed vertical slot 18 angled slot 19 and-on the. rightgot the T neutral .slot an -.obtuse angled slot '20. These three slots are adapted to-be engaged-by pro-,

jections carried-by a-drum .or whejel 21 ffor whichpurpose the slots merge into the,op-=

slots being slightly widened to proVide an easventry for the said projections. The projections referred toconstitute part of a number-of plates23 (see Fig. ;5),, the projections '24 being disposed at opposite 'endsof said plates, These platesarer adapted to have an even and comparatively tight fit. in a number-"of radial and transverse slots, 25 disposed across the periphery of the drum 21. v Provided around. the. centre of the :peripheral surfaceaof -the drum 21 i a circu mfere'ntialslot 26 about'half the depth 'posite Side. P ons 22 of the channel. mb ri't to allow the projection w e gage therewith, the upper portion of. the

of the transverse slots 25 and sprung into this. circumferential slot is a, coiled spring band 27. This spring band 27 serves to maintain the plates 23 inselected positions in the transverse .slots 25, and for :this pur pose the said plates are eachprovided along their edges disposed furthestfrom the centre of the drum with three semi-circularslots,

hereinafter referred? to as the neutral slot, 8 v, Disposed on-the/left (see I Fig. 2)- of :thisneutralislot isa Vshapedori acute i a, b, and 0, which slots are adapted to be ti htly engaged by the spring band 27,- so that each plate is capable of being set and maintained in any selected one of three lateral positions relatively of the drum 21. When the plates 23 are in position in the drum 21 the projections 24 extend beyond the periphery of the said drum in such a manner that one of each pair of the projections willengage one of the three slots 18, 1 9, in the channel member'll'; hould a plate be arranged in atransverse slot so that a projection 24 will engage the neutral slot 18 the projection will pass straight through said slot without affecting the posi tion at the arm 7 so that the flag 1 will not be moved. Should however it be desired to signal a d ashm rith the flag the plate 23 would be so positioned in a transverse slot so that a projection 24 will engage the V shaped or acute angled slot 19, the downward pressure of the projection upon the edges of such slot iiiipa-rting a comparatively wide sweeping movement to the said flag. SimilarIy should a be desired to sigrial a d otthe plate 23 would be positioned for projection to engage the obtuse angled slot 20: H s 4 The position of the plate shown in Fig. 6 and the plates in Fig. 4 are for sending riots from which it will be seen that the central semi-circular slot 5 is engaged by the ('joile'd spring band 27; for sending adash the slotc is engaged by the said spring band, and for neutral position the slot (4 is ehgaged. For clear ness the slots areshown in Fig: 5 with the corresponding signal marked eppqsiteeacn, the letter 'N indicating neurial. If desired similar or equivalent marking may be "efl'eoted in practice.

' It will be seen from Fig. 4 that when a plate seem signal a dot oneprojection 24 engaged the obtuse angled slot 20 and when sending a wash the other projection enga'ge's the V shaped 'slot in both cases the non engag'ing projeotion clearing the channel member 17. Similarly in the neutral ,p'o 'sitioatnesameprojection used for the dot passes through the slot 18 whilst the remaining projection clears the said" channel memher, If desired ewe colored rings may be marked aroundfthe periphe al surface of the 21 to indicate the positions opp o site which theprojections 24 should be set for dash and neutral positions. I

Irwin be clear that by setting the plates. selected positions and rotating the drum 21," a corresponding to the selected positions ofthe plates will be signalled by ehe'nag 1. A starting" position on the drum '21 may be pro 'ide'd by omitting a slot as at 28 (see Fig'1) 6r by a colored mark.

The drum supported for rotation by $5 bearings 29, a spindle 30 carried by said anaengaging said bearings beingprm vided for this purpose. The bearings are detachably supported in the casing 10, by means of threaded pins 31 carried by said bearing-s engaging bayonet slots 32 provided on oppositesides of the casing 10; milled clamping nuts 31 being screwed on to the outwardly projecting parts of said pins '31. lhe casing 10 is made in two parts the top part 10 having one end wall omitted to enable it to fit over the end wall 9, the top of this part 10 being shortened slightly to leave a clearance 83 through which the flag arm 2 projects. i 3

Rotary motion may be imparted to the. drum 21 by any suitable means, a preferred means being that illustrated by the drawings in which a relatively small wheel 34 is provided having a circumferential rubber band 85 engagii'ig the inner face of a concentric upstanding rim 36 formed on the drum 21. A handle 38 is provided for rotatingthe wheel 34. Alternatively the rim 36 may take the form of a toothed annular and the wheel 34 be'corres'pondingly provided with teeth, or a worm drive may equally well be provided.

A further means or visual signalingi's by means of a lamp 39, suitably connected to a source of electric current such as adry cell dO, the lamp being included in the ciredit by vmeans or a contact 41 on the arm 7 engaging a spring contact tinge-r42 connected to one terminal ofthe cell and carried by an insulating blocl 43 secured'to'the end wall 9. Likewisea means of sound ing such as; a buzzer 44 be similarly connected to the cell 40 so that the three means of signaling may be used simultaneously. g I For switching the buzzer and lamplinto circuit a pair of t ontacts 45, 16, are'prm vided over which adapted to be moved an arcuately movable contact finger 47, sojtha t either the lamp 0 1' the buzzer maybe selected, or by bridging the contacts both' 'of them be used simultaneously; H

As an alternative'means of contact the arm 7 may be provided with a spring finger adapted to engage a contact (thequivaient of the Contact 42) the position 'of which may be adjusted so that-"the periodicitiesof the dots and dashes may b'ejvaried. Ln'ff It will be'ap'parent thatth'e Contact the arm 7 will remain incontact with the spring contact 42 longer during the'se'nding of a daislfthah during the sending of a dot so that the lamp or buzzer will be illuminated or sounded for a time correspohding to the nave-meat o'f'the flag 1;.

To'tnaintain the drum 21 in correct ali nmerit duriflgits rotation a pin 48 is' previded projecting from the plate 13 havin along;- tiidinal head 49 engaging the slot 26.

If desired an ordinary signaling l'zeyr'n'ay be connected the lamp-and buzzer so that signaling may be efiected Without rotation of the wheel or drum 21.

I Wish it to be understood that modifications may be effected in the apparatus hereinbefore described without departing from the spirit and scope of my invention.
